Installation

npm install @sucoza/graphql-devtools-plugin

Quick Start

Basic Setup

import { GraphQLDevToolsPanel, createGraphQLDevToolsClient } from '@sucoza/graphql-devtools-plugin';

// Create the DevTools client
const graphqlDevToolsClient = createGraphQLDevToolsClient();

// Add to your app
function App() {
  return (
    <div>
      {/* Your app content */}
      
      {/* DevTools panel */}
      <GraphQLDevToolsPanel />
    </div>
  );
}

With TanStack DevTools

import { TanStackDevtools } from '@tanstack/react-devtools';
import { GraphQLDevToolsPanel } from '@sucoza/graphql-devtools-plugin';

function App() {
  return (
    <div>
      {/* Your app content */}
      
      <TanStackDevtools>
        <GraphQLDevToolsPanel />
      </TanStackDevtools>
    </div>
  );
}

Configuration

Schema Introspection

Configure endpoints for automatic schema introspection:

import { createGraphQLDevToolsClient } from '@sucoza/graphql-devtools-plugin';

const client = createGraphQLDevToolsClient();

// Add GraphQL endpoints
const schemaManager = client.getSchemaManager();
schemaManager.updateOptions({
  endpoints: ['http://localhost:4000/graphql', '/api/graphql'],
  autoIntrospect: true,
  cacheTimeout: 300000 // 5 minutes
});

Custom Headers

Add custom headers for authenticated endpoints:

// Introspect with custom headers
await client.introspectSchema('http://localhost:4000/graphql', {
  'Authorization': 'Bearer your-token',
  'X-Custom-Header': 'value'
});

Network Interception

The plugin automatically intercepts GraphQL requests. Configure interception options:

const interceptor = client.getInterceptor();

interceptor.updateOptions({
  enabled: true,
  endpoints: ['/graphql', '/api/graphql'],
  autoDetectEndpoints: true,
  maxOperationHistory: 1000
});

API Reference

GraphQLDevToolsClient

const client = createGraphQLDevToolsClient();

// Schema operations
await client.introspectSchema(endpoint, headers);
client.getSchemaManager();

// Query builder
client.setQueryBuilderOperationType('query' | 'mutation' | 'subscription');
client.addQueryBuilderField(field);
client.generateQuery();
client.validateQueryBuilder();

// Operation management
client.clearOperations();
client.getFilteredOperations();
client.exportOperations();

// UI controls
client.selectTab('operations' | 'schema' | 'query-builder' | 'performance');
client.toggleRecording();
client.updateFilters(filters);

React Hooks

import { useGraphQLDevToolsStore } from '@sucoza/graphql-devtools-plugin';

function CustomComponent() {
  const state = useGraphQLDevToolsStore();
  
  return (
    <div>
      <p>Total operations: {state.operations.length}</p>
      <p>Schema loaded: {state.schema.schema ? 'Yes' : 'No'}</p>
    </div>
  );
}

Example Application

The example/ directory contains a full demo application showing all features:

cd example
npm install
npm run dev

The example includes:

• Mock GraphQL server with sample schema
• Sample queries and mutations
• Interactive demo interface
• DevTools panel integration

Development

Building

npm run build

Testing

npm test
npm run test:ui

Development Mode

npm run dev

Type Checking

npm run typecheck

Schema Requirements

The plugin works best with GraphQL schemas that support introspection. Ensure your GraphQL server has introspection enabled:

// Apollo Server example
const server = new ApolloServer({
  typeDefs,
  resolvers,
  introspection: true,  // Enable introspection
  playground: true      // Optional: enable GraphQL Playground
});
